		<li>Added so called barrier functionality, which is a set of commands to easy implement a barrier. A barrier is some point in time during execution of a test which if reached can trigger some action. For details have a look into commits <a href='https://git.gnunet.org/gnunet.git/commit/?id=34e1c58cb39a649c9a4c551681cedf19807b85f0'>34e1c58cb39a649c9a4c551681cedf19807b85f0</a>, <a href='https://git.gnunet.org/gnunet.git/commit/?id=ba4d141be09651b452270fc21f062d50bd3f738a'>ba4d141be09651b452270fc21f062d50bd3f738a</a> and <a href='https://git.gnunet.org/gnunet.git/commit/?id=2c2b2911e1585dc378dbb88d4dd6aaec37b00316'>2c2b2911e1585dc378dbb88d4dd6aaec37b00316</a>.</li>

	  The outcome of the performance measurement was 20 MByte/s for packet size of 65000 bytes.

	  For this measurement the TNG layer was using tcp only, because there was an unfixed bug, if running tcp and udp in parallel.
